CORN-SHELLER.

Speccaton of Letters Patent No. 18,325, dated October 6, 1857.

T o all whom 'it may concern.

Be it known that I, A. M. COOK, of Milford, in the county of Vorcester and State of Massachusetts, have invented a new and Improved Co-rn-Sheller, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is a plan of an improved corn Sheller, part of the frame and upper disk being broken away to show the perforated toothed plate. Fig. 2, is a side elevation of the same, part of the exterior case being broken away to show the parts within.

In the drawings, A, is the frame of the machine, on suitable bearings on the top of which is supported the horizontal driving shaft B, which carries a beveled cogged gear C, which engages with another bevel gear on the top of a vertical shaft D, this shaft passes down through the center of the machine and is supported in a suitable step at a, on the cross brace E, of the frame, and by the iron brace F, through which it passes, this brace being secured at each end to the sides of the frame.

To the shaft D, just above the lower cross braces of the frame A, is secured a disk K, of cast iron or other suitable material which is revolved by its shaft in a horizontal plane. This disk' is formed of a sufficient thickness to render it rigid, it is perforated with holes c, and has projecting from its upper surface series of short strong pins z'. Above this plate and secured to the under side of the cross braces E is another disk Gr which may be made of wood or metal, this is stationary and supports a hopper I-I, which slopes down toward a circular opening Z) in the disk G, to the under side of this disk are secured four radial arms I which extend from the opening b, to the periphery of the disk, and reach down to within a short distance of the teeth o, on the disk K, a metal guard g, is also secured to the under side of the disk Gr, this is formed as shown in elevation in Fig. 2 and in plan in red in Fig. l. The outer end or that toward the periphery of the disk lying in a plane parallel to the radial arm I, and the inner end being bent off at an angle to such plane is secured at 71 to the face of the next adjoining radial arm I, this leaves a considerable space between the guard g, and the opening A block M, lies parallel to each arm I, and

is attac-hed thereto by screws K, passing through slotsin the arm, it is steadied between the arm I, and the part of the guard g parallel thereto, it is slightly beveled off at its lower edge on the side next to the guard g, as at Z, and is pressed down by two spiral springs m, placed between it and the disk G.

Near the bottom of the frame A is secured an inclined sheet metal t-able O, which receives the shelled grain as it falls through the holes c in the disk K, and conducts it from the machine.

The frame A, is inclosed on each of its four sides by sheet metal casing N, which prevent the grain from being thrown out by the centrifugal motion given by the revolution of the disk K. One of these casings is furnished with a sliding gate 71 which is raised to allow the grain to escape off the table O.

The teeth of the disk K are arranged in series, each series being arranged in lines at right angles to a radius of the circle, the revolution of this disk gives to the cob a centrifugal movement at the same time that it is rolled over by the teeth in contact with the arm I, and is held down by the block M.

The operation of this machine is as follows: The ears of corn are thrown, in suitable quantities into the hopper H, whence they pass down through the opening ZJ, and are received on the disk K between the guard g and the opening b, whence they pass in succession between the arm I, and guard g, and beneath the block M, which keeps them down in contact with the teeth z' of the disk K, by which the ear is rolled over against the arm I, and the grains are stripped from the cob,-the grains falling through the holes c, in the disk K, onto the inclined table O, by which they are conducted out of the machine, the cob being still kept with its axis parallel to the arm I, is caused by the motion of the disk K, to work toward the periphery of the disk, but before it reaches this part of the circle it is entirely stripped of its grains, and the shelled cob is ejected from the machine through suitable openings as at p in the casings N.

The machine represented in the drawings is made with but four radial arms I, but any convenient number may be used to suit the capacity of the machine to the dimensions of the disks and the amount of power to be used, and although the ears of corn pass in succession between the guards g and What I claim as my invention and desire to secure by Letters Patent, is-

The perforated revolving disk K, in combination With the radial arms I, guards g, l5

and blocks M, constructed and operating in the manner and for the purpose substantially as herein set forth.
